PAD FOR SOLE-LAYING MACHINES.

Specification of Letters Patent.

PatentedAug. 10, 1920.

Application filed April 29, 1919. Serial No. 293,510.

To all whom it may concern Be it known that I, MAIuUs METHILTUSSiGRENSEN, a subject of the King of Denmark, residing at Vallerod, inthe island of Seeland, in the Kingdom of Denmark, have inventedcertain'new and useful improvements in Pads for Sole-Laying Machines, ofwhich the following is a specification.

This invention relates to means by which there can be convenientlyprovided an effective and accurately shaped pressure under layespecially adapted for sole laying machines for use during the variouspressure operations occurring in soling, rubbing down, etc.

The device consists of a system of uniformly shaped members disposedside by side in longitudinal and transverse rows. The ends of certain ofthese members and sides of certain of the other members form the desiredunderlay surface, and the members are movable in a direction at right orapproximately right angles to said surface and can be secured inadjusted positions, so that, after being put into the right shape bybeing applied to a model or the sole of a model shoe, the underlay canbe secured in this shape, and, after use, can be shaped on other models.

One form of this device is, by way of example, diagrammatically shown inthe accompanying drawing. Figure 1 is a longitudinal section of thedevice; Fig. 2 trans verse section; and Fig. 3 plan view respectively.

In the drawing the rod shaped members t have longitudinal slits 5 bymeans of which they are suspended in rows on wires or rods 6, which arefixed to one end piece 7 of a frame 8 and run freely throughcorresponding holes in an opposite stretcher-block 9, having a softpressure-surface. Each member can, independent of the others, be shiftedaxially up or down over a distance corresponding to the height of theslits 5 (minus the diameter of the wire 6), and each row of members byitself, or all the rows to gether, can, notwithstanding the altitudinalposition of the various members, be secured against axial movement, soas to form a complete block, by tightening one or more screws 10, or thelike.

When the members are unsecured, 2'. 6.,

when the screw 10 is not tightened, and the device is held in such a waythat the members, with their rounded or otherwise suitably shaped ends,are allowed to move downwardly from above against a model or the sole 11of a model boot or shoe, the member will assume such positions thattheir ends will form a surface of just'the shape which the desiredresistance surface should have, and these positions they will retainwhen the screw 10 is tightened. Not only will the various members ineach row assume the various altitudinal positions that correspond to thelongitudinal curve of the shoe or boot sole, but in the transversedirection the member will assume various altitudinal positionscorresponding to the transverse curve of the instep and other parts, andsome of the members will wholly or partially receive the lateralpressure.

The described device will thus act, in principle, like a plasticmaterial, which can be hardened after shaping.

The shown details are illustrative of the invention and may be modifiedin many different Ways. For instance, the members need not lie in directcontact with each other and be held together by means of their mutualpressure, either in the longitudinal direction, as shown in the drawing,or in its transverse direction, but they may be inserted into holes orslits in two or more plates, or the like, and be held fast by means ofsqueezing, as a result of relative shifting or turning of these plates.Likewise the limitation of their shiftability or their connection withthe utensil may be attained in many other ways than that here shown.

I claim 1. A pad for sole laying machines comprising a frame, a seriesof longitudinal and transverse rows of axially movable members mountedin said frame, and means for looking the members against axial movementin either direction after they have been placed in adjusted positions.

2. A pad of the kind defined in claim '1 in which the members arelongitudinally slotted and rods carried by the frame extend through theslots.

In testimony whereof I aliix my signature.
